IMPROVEMENT m LAMP-SHADES,

The Schedule referred to in theseLettera Patent and making part of thesame.

1 of forming the covering of a lamp-shade, and consists in forming thecovering or screen"from an entire sheet of paper or other similarmaterial suitable for such purpose, having its exterior cut to a radiatesection form, so that when the contiguous edges of the several sectionsare brought together and secured, they will give to the shade a hollowpolygonal form, suitable for such purpose as will be described.

My invention relates in the second place to the method of securing theedges of the several sections togetherwheu socut to form, and consistsin covering and overlapping the joint, when the sections are placedtogether in form, by a strip of paper or other suit-able materialattached to the sections by some adhesive .matter,-and made ornamentalor otherwise, as may be desired. I g My invention relates in the thirdplace to the construction and adaptation to the paper or othercovering'before inentioned-ofa light metallic frame, for the purpose ofkeeping the shade in shape and fur .nishing a means for supporting thesame upon the lamp, and consists in combining with the covering ametallic spider, theouter arms of which rest in the angles between thesections of the covering and keep the same in shape, and the inner endsof which arms, when required, project inward, and are bent up and down,so as to serve as a yielding and self-adapting support for the shade byembracing the exterior of/ the chimney.

And finally, my invention consists of a lamp-shade, constructedsubstantially in the manner before mentioned, as a new manufacture.

Description.

In the drawings- Figure 1 represents shade g Figure 2 is an elevation,one-half invertical section; and

Figure 3 shows the form in which the sheet of paper is cut to give therequisite form to theshade.

A is the shade or covering, made of a sheet of paper or any appropriatematerial, and colored or otherwise ornamented as may be desired, whichis first cut to the radiate or sectional form shown in fig. 3, by meansof suitable cutting dies or by a pattern, leaving a large hole, A, inthe center, as is shown.

, The several sections of the paper are then bent over in acurved formupon asuitahle mold or former,

a plan of the inside of the so as to bring their contiguous edgestogether, as is shown in fig.'2, in which position they are secured bythe strips B, which overlap the joints on the outside, and are attachedto the covering by paste or other suitable adhesive material.

Similar strips are also applied to the upper and lower edges of theshade to make an appropriate finish. These strips I prefer to make ofadifferent color from the body of the shade, and their edges may be cutto some ornamental form if desired. The panels inclosed by these stripsmay be further ornamented by some appropriate device or vignette printedor embossed upon them.

After the shade has been brought to the form shown, there isplacedwithin it the metallic frame 0 D, which is made with light radialarms 0, made of 'fiattenedwire, which are joined at their intersectionto the light wire ring Dby soldering.

The arms G restin the angles formed by the sec tions of the shade, andthe lower end of each is secured to the shade by a small piece, E, ofpaper or other material, which is attached to the inside of the shade bypaste or cement, and passing inside of the arm, incloses its lower endand connects it with the covering.

The inner ends of the arms project inward beyond the central opening ofthe shade, and are alternately bent upward and downward, as shown, so asto yield and embrace the exterior of the lamp-chimney with sufiieientpressure to support the shade upon it, while it leaves asuflicientlylarge free space between the shade and the chimney toprevent the shade from being' scorched by the heat. There is also some.:i'ree space left between the frame and the covering at the top, asshown, to vpermit the free expansion of the frame by the heat withoutdistorting the shade or communicating heat to it by the frame.

I What I claim is-- v 1. A lamp-shade, made in a polygonal form, from an'entiresheet of paper or other suitable material, by

cutting the same to a sectional and radiate form, and then bringing thecontiguous edges of the sections togetlier and securing themsubstantially as described.

2. In combination with a lamp-shade so out and formed, the strips B foruniting the several sections, substantially as described.

3. In combination with. a lamp-shade, made of a sectional and polygonalform, the metallic framewith its arms. resting in the angles of thesections, in the manner and for the purpose described.

4. The lamp-shade, constructed substantially as described, asanewmanufacture.
